MACHINE FOR FORMING HOOKS ON WIRE BALE-TIES.

SPECIFIGATION forming part of Letters Patent No. 748,580, dated January5, 1904.

Application filed April 21,1903.

To all whom it may concern:

Be it known that I, BRUNO VON BiiL'rzING- SL6WEN,a subject of theEmperorof Germany, residing at New York, in the county and State of NewYork, have invented certain new and useful Improvements in Machines forForming Hooks on Wire Bale-Ties, of which the following is aspecification. I 1

These improvements relate to the same type of machines as described inmy application, Serial No. 103,199, filed April 16, 1902, and are fullydescribed in the following speci-' fication with reference to theaccompanying drawings.

The main object of my present invention is to improve my aforesaidprevious construction, so as to simplify and facilitate the differentmovements-that is to say, to provide means for automatically bending thewirethereby facilitating the work formerly performed by the operator andfor strictly confining the wire in place before and during the bendingoperation, so as to allow bending of even the strongest wire used inbinding haybales.

Another important feature of my improved construction is the use of acoupling device which can be thrown into engagement by the leastpossible power and which results in a tight hold of the coupled shafts,nevertheless allowing an easy and automatioal disengagement of the same.

In the accompanying drawings, Figure 1 is a plan view of a machineembodying the afore-' said improvements. Fig. 2 is a plan view of thesame, taken from underneath the baseplate. Fig. 3 is a front elevationof the ma chine, the base-plate being cut away, so as to expose allparts below the same. Figs. 4 and 5 are cross-sections on line 4 4 and 55, respectively, of Fig. 3. Fig. 6 is a detail front view of theprincipal parts of the hook-bending mechanism in inoperative positionprior to the bending operation. Fig. 7 is a similar view showing theposition of the parts at the completion of the bending operation, thebent wire being in place. Fig. 8 is ,a detail end view of thehook-bending mechanism. Fig. 9 is a detail cross-section of the same.Fig.

ing the twisting operation, the wire ends being shown in section and'allparts in their operative position. Fig. 11 is a detail plan view of theclamp device. Fig. 12 is a detail longitudinal section of the newcoupling device. Figs. 13 and 14 are respectively a detail front viewand plan view of the lever for bending the free end of the wire towardthe long end of the wire body. Figs. 15 and 16 are respectively a detailfront view and a plan view of the cam projection effecting the retn rnmovement of the main lever for the operation of the hook-bendingmechanism, and Fig. 17 is a side View of a hook bent on my improved 7machine.

Similar letters of reference indicate corresponding parts throughout thedrawings.

A represents the base-plate, supported so as to allow arrangement ofmechanisms above and below the same. A rocking lever K is pivoted to abracket or upon the base-plate, embracing with its upper forked end asliding sleeve B upon the main shaft 0, the latter being journaled inbearings A and A upwardly projecting from the base-plate A. The forkedend of lever K carries frictionrolls h in engagement with the projectingside flanges of sliding ring B, which is fastened to its shaft by splineconnection. At the left-hand flange of the sliding ring B, Fig. 3, threepivot-carrying ears I) are provided, which by means of links df f servefor operating the hook-bending mechanism; The latter comprises thefollowing parts: A circular head 0 on the main shaft 0, having lateralrecesses cto receive two of the ears I) of sliding sleeve 13. Aflattened head portion cast integrally with the forwardlyprojectingplate E, on which the hook-bend ing mechanism is mounted, is screwedonto the circular head 0. A wire-bending lever E bent at a certainangle, so as to correspond with the shape of the hook, is laterallysecured to arm E, which is fastened upon a pivot e journaled in theplate E. A pin e projects eccentrically from the forward end of thepivot 6 while a pinion-E meshing with another pinion E, is keyed on theopposite end of the same. The pinion E is rotated by the sliding sleeveB through the medium of link f and. crank f. The hookbending lever Fturns loosely upona studf,

projecting from the lower part of the plate E,

and forces wire 2 round a pin 6. A cam-surface f of lever F operates athird lever E also pivoted to the plate E, against the tension of aleaf-spring 6 The left-hand upper end of lever F, Fig. 7, is providedwith an upwardly-projecting support f for lifting up the long end of thewire body z and securing both ends of the bent hook in proper positionfor the clamp device, which will be described later on. A link fconnects lever F with the sliding ring B.

The mechanism for tightly holding the bent hook in its position whilethe ends thereof are twisted around each other consists of a lock-plateD, sliding with its lower cut-out portion in acorrespondingly-formedplate D, which is screwed upon the plate E. A coverplate D is fastenedon plate D,.overlapping the aforesaid cut-out portion, thus resulting ina tight hold of plate D, which may be shifted by the sliding sleeve Bthrough link (1. At the end of the plate E a spring-sup- "ported lock eis provided, which keeps the long end of the wire body in a straightline during the operation of the hook-bending lever F. This look a isacted upon by a lateral projection e of the wire-bending lever E againstthe tension of a leaf-spring e The clamp device for tightly gripping thewire ends during the twisting operationconsists of a bracket A screwedupon the baseplate A, and a support-plate G, laterally projectingtherefrom. The upper end of the bracket A at its inner face possesses adie g, which forms in connection with a similardie g on a rockingclamp-lever G a proper support for the wire ends 2. This rockingclamplever G is pivoted to plate G and acted upon by a roller gjournaled at the outer end of an oscillating double lever Gr, alsopivoted upon plate G. A spring 9 draws the rocking lever Gr back to itsnormal position. The oscillating lever G is turned upon its pivot, so asto act upon or release the clamp-lever G by means of a rod G slidingvertically upon its longitudinal recess g, and an angularconnecting-link G The rod G3 projects through a suitable opening ofbase-plate A and carries at its lower end a lateral projection g. Thesupport-plate G has at its upper edge a groove 9 as guiding means forcorrectly inserting the wires 2, this groove g being in a vertical planewith the dies g g when they are in their operative position.

The means for automatically operating the hook-bending mechanismconsists of the following parts: A bearing V is screwed underneath thebase-plate A, carrying shaft S, to

c the forward end of which a disk N is fastened, being provided withseveral projections and cam-surfaces. .A semicircular plate N,integrally cast with this disk N, lies in its inoperative position withits diametrical edge against the main lever K for operating the Abracket 0, se-

cured underneath the base-plate A, has laterally-projecting guide-rails0, undercut, so as to tightly secure and guide a rod M, one end of whichcarrying a friction-roller m, lying against the main lever K, while tothe other end an upwardly-projecting arm m is laterallysecured. Theouter end 72 of an abutment n rests just below this arm m before themachine is started. Another semicircular cam N is provided upon theperiphery of disk N in such position as to operate the clamp device forsecuring the wire ends 2 during the twisting operation.

L'indicates a bracket downwardly projecting from the base-plate A.Pivoted to the bracket are an angle-lever L and a double lever Lconnected by means of a link L and carrying at their free endsfriction-rollersl and Z, respectively.

The roll Zrests upon the lateral projection g of the vertical rod G anddepresses the latter against the tension of a spring g whenfriction-roller Z is depressed by and running upon the cam N The meansfor starting the machine comprise a foot-lever (not shown in thedrawings) acting upon an angle-lever V which is fulcrumed at a bracketV, downwardly projecting from bearing V, and a coupling device of asimple yet very efficient construction. A cylindrical casing S ismounted upon shaft S by a spline connection 3 This casing S has acut-out portion 8, so as to allow insertion of a spiral spring 8surrounding shaft S, while the inner end of this spring is supported atthe end of boring s. The movement of the spring in the oppositedirection is limited by aring S secured on shaft S. The flange S of thecasing S has outwardlyprojecting coupling-fingers s,which are inposition to engage corresponding projections s of bevel-gear P, looselymounted on the rear end of shaft S. The left-hand flange of the casingS, Fig. 4, has a boring for a pin v, secured at the rear face of bearingV, thereby limiting the rotation of coupling S to just one revolution.The bevel-gear P meshes with a smaller gear P, secured on one end of ashaft U, which is journaled in a bearing U under the base-plate A. Theother end of this shaft carries a chain-wheel U which is operated bymeans of a chain and another chain-wheel I from the main shaft 0. Thechain-wheel I is secured upon the hub of a driving pulley I, which isloosely mounted upon shaft 0, the same coupling, as above described,being used for throwing this pulley into engagement with its shaft. Thecylindrical casing H is mounted upon shaft 0 by a spline connection h. Aspiral spring 72?, which is placed in the cut-out portion h, is limitedin its movements by a ring H tightly secured upon shaft 0.Coupling-fingers h are provided at the end flange H so as to engagecorresponding coupling-fingers h, laterally projecting from the pulleyI. The opposite end flange H is acted upon by IIO , ima e a rockinglever K, whichthrows the coupgle-lever R, which rocks lever K by meansbearing A of a friction-roller R thereby throwing the coupling on themain shaft into engagement. At the same time a pin 7c, laterallyprojecting from lever K into a boring of a disk T,

mounted upon an axle T, releases said disk,

which starts to rotate on accountof its connection with the main shaft0.

O and T represent chain-wheels in a ratio of one to three,therebyallowing three revolutions on the main shaft 0 during one revolution ofaxle T, the latter being mounted in bearings A A underneath thebase-plate A. A bracket R, to which the angle-lever R is pivoted,projects downwardly from the bearing A, while the rod t is screwed intothe A spring 10 connects said rod t with the lower end of lever K.

The operation of the machine is as follows: The pulley I may be operatedby any suitable power whereby by means of the chainwheel connection I Uoperation is transmitted to the bevel-gear P. On depressing thefoot-lever, which is not shown in the drawings, this bevel-gear P isthrown into engagement with its axle S; but on account of the pin 0 andits corresponding recess in the coupling S the operation will be limitedto one revolution only. The Wire ,2, which is placed in the machine in aposition indicated in Figs. 3 and 6, is bent through the rotation ofdisk N. The moment the machine starts the cam N actuates the main leverK, the lower part of which is pushed to the right to a positionindicated in dotted lines in Fig. l

3. During this progress the hook is bent and tightly kept in itsposition by lock-plate D. The heel f of the hook-bending lever F haslifted the long end of the wire body so far as to bring it in closecontact with the short end of the bent wire, thereby placing both in 'aproper position for the gripping device, which by means of theactuating-cam N operates immediately after the hook is bent. While thehook-bending lever F performs its operation, the spring-supported lock 6serves as abutment to keep the long end of the wire body in a straighthorizontal line. This lock is, however, removed from the path of thebending-lever E by the projection e of the latter shifting the lock eback against the tension of its leaf-spring e so as to allow the wire topass. As soon as the wire ends are tightly secured in the recess 9 g thelever K is turned upon its pivot by means of the lateral abutment n ofdisk N, passing angle-lever R and forcing the same into the dotted-lineposition of Fig. 3. The upper end of the lever K throws thereby thecoupling H into engagement with the driving-pulley I, and as at the sametime the pivot 7r has released disk'T the latter starts to rotate in theratio of the chainwheels (J and T After the-abutment 'n has passedangle-lever R lever Kis kept in its position by pin it sliding on theside of disk T until one revolution of the same is completed, when,following the tension of spring lever K locks disk T and disengages thecoupling H of the driving-pulley I. At the same time guide-rod M ishorizontally shifted through the medium of the abutment n n striking theupwardlyprojecting arm m. The friction-roller m at the other end of theguide-rod M thereby draws back the main lever K to, its normal position,whereby the finished hook is exposed, so as to be easily removed, theclamp device having retion-roller Z of the oscillating lever L hasslipped from the actuatingcam N and under the tension of spring g allparts have returned to their inoperative position. At the same time theautomatical coupling S is thrown out of engagement with the revolvingbevel-gear P after one complete revolution, as pin 12 enters the boringin the side flange of the casing S.
